So I went and used my truck today...Couple cold cranks and she fired right off. When hot..takes only 1/2 a crank. The new HEI makes a heck of a difference...pulled my plugs for an exam...and we are running just a tad hot. Might need to go a step cooler...but I think as long as I'm running 92 octane I should be good...runs like a dream...now time for some nitrous!
